The two-dimensional structure of graphene allows scientists to stack sheets of it together to create the thin membrane. Mi explains that by adding oxygen to graphene to make graphene oxide, space is created in the structure for the water to flow through. One problem with this approach is that adding oxygen makes the graphene more likely to dissolve in water. However, when Mi adhered a chemical to the sheets of graphene oxide to join them together, she found the membrane stayed intact in water.
So without an extra chemical, the graphene dissolves directly in the water. Is graphene itself as bad for you as graphene oxide?
Let's not forget graphite is a chemical derivative of Graphite
The stuff pencil lead is made of.
Their atomic structures are both hexagonal, but graphene is made of graphite molecules interwoven to increase it's strength

Yes graphite is used in pencils, but it's not lead - it used to be but they replaced lead with graphite.
People still call it pencil lead out of habit I guess, it rolls off the tongue easier.
I believe when people speak of graphene they are speaking of graphene oxide chains.
